Title: Magnetoresistive element
Inventor: SAKUMA AKIMASA
IPC: H01L43/08
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To obtain a higher magnetism-sensing factor for a magnetoresistive element, which is constituted by laminating ferromagnetic layers with a non-magnetic layer between them, by a method wherein the non-magnetic layer is formed as an NiC4 layer, and at least the ferromagnetic layer on one side of the ferromagnetic layers is formed as an Fe or FeNi layer. SOLUTION: In a magnetoresistive material, which is formed by laminating ferromagnetic layers with a non-magnetic layer between them, the non-magnetic layer is formed as an Ni1-y Cuy (0.3<=y<=0.9) layer and at least the ferromagnetic layer on one side of the ferromagnetic layers is formed as an Fe or Fex Ni1-x (0.15<=x<=0.6) layer.  Whereupon, if Ni atoms are previously made to contain in the NiCu layer, which is the non-magnetic layer, from a mechanism that the magnetic moment of an Fe atom is augmented by an Ni atom and a developing mechanism of a magnetoresistive effect and Fe or a permalloy alloy is used for the ferromagnetic layers, the spin of the Fe atoms come out of the interfaces between the non-magnetic layer and the ferromagnetic layers or the ferromagnetic layers is largely subject to spin polarization by the interaction between the Fe atoms and the Ni atoms in the non-magnetic layer. As a result, there is a possibility that the magnetoresistance material can obtain a high magnetoresistance changing rate. When such a magnetoresistance element is used for a magnetic sensor, a strong regenerative output is obtained.

Title: Percolation type hot-water boiler
Inventor: TERAOKA TOYOKAZU
IPC: F24D3/00
Filed: 1983-03-18
Abstract: PURPOSE:To facilitate the manufacture of the titled boiler and to reduce water cutting sounds by a method wherein a bypass body having a hole of large diameter and a throttle pipe having small inner diameter are provided in a hot water bypass pipe connecting a forward heating pipe and a backward heating pipe in that order and a ball valve is arranged midway in the bypass body. CONSTITUTION:A throttle pipe 12 is arranged in the bypass pipe 11 which connects a forward heating passage 5 and a backward heating passage 7 and a bypass valve 10 is formed of the bypass body 10a and the ball valve 10b of a diameter smaller than that of the bypass body 10a. The inner diameter of the throttle pipe 12 is made smaller than that of the hole in the bypass body 10a and is so determined that hot water in a quantity larger than a predetermined value is allowed to flow through the pipe 12 lest the hot water should boil in an instantaneous heat exchanger 1. Thus, by the provision of the throttle pipe 12 in the bypass pipe 11, it is not necessary to correct any displacement of the center of the hole of the bypass body 10a from the center of the hole in the ball valve 10b so that the boiler is manufactured easily and the cavitation at the downstream side of the bypass body 10a is prevented to thereby reduce noises.

Abstract: PURPOSE:To improve the stability of a multistation processing system by providing a 2theta angle adjusting mechanism to a first beam switching mechanism and installing a beam position sensor, beam profile monitor and power meter near to the final beam switching mechanism. CONSTITUTION:The laser beam 13 emitted from a transmitter 2 passes through the beam switching mechanisms 3, 5, 6, 7 and the beam position is detected by a thermocouple type beam position detector 8.

The detection signal of the beam profile monitor 9 passes through a resonator alignment control box 11 and is fed back to the resonance alignment 11 to correct the mode if abnormality is judged. Further, the detection signal of the power meter 10 is fed back to a power supply 1 and the stable laser beam 13 is taken out to operate the respective beam splitting/switching mechanisms so that the beams are transmitted to the respective processing stations if said signal is defective in power with respect to the set value.

Title: Manufacture of highly water-absorptive polymer
Inventor: ITO KIICHI
IPC: C08L33/02
Filed: 1987-02-27
Abstract: PURPOSE:To obtain the title polymer having a high strength and a uniform particle diameter, by subjecting an acrylic acid monomer to water-in-oil type reversed phase suspension polymerization, adding a dried powder of a highly water-absorptive polymer and water to the polymerized liquid, and effecting azeotropic dehydration of the water in the polymer. CONSTITUTION:An acrylic acid monomer which comprises (meth)acrylic acid, its alkali metal salt and/or ammonium salt as main components, and a water-soluble radical initiator are dissolved in water. Then, the aqueous solution is dispersed in an organic solvent, and subjected to water-in-oil type reversed phase suspension polymerization. To the resulting polymerized liquid are added a dried powder of a highly water-absorptive polymer and water. Then, under reflux of the organic solvent, the azeotropic dehydration is continued until the water content of the polymer reduces to 20wt.% or below to obtain the aimed highly water-absorptive polymer. This polymer is superior in flow properties, miscibility, dispersibility, etc., and can be suitably used for the production of sanitary materials.

Abstract: PURPOSE:To eliminate a solvent in removing a polarization electrode and to simplify the manufacture steps by forming an electrode on both faces of a dielectric substrate and forming many strings of closed-ring shape electrode eliminating ridges to the electrode of one side of the substrate so as to cut off the perimeter of the electrode eliminating ridges. CONSTITUTION:A conductive paint is applied to both faces of the dielectric substrate 1 or the polarization electrode 2 is formed to the upper/lower faces by silver baking.

Many closed-ring shape electrode eliminating ridges 3 are formed to the electrode 2 of one face of the substrate 1. The perimeter of the ridges 3 is cut off as a rectangle along a cut-off line (l) and each pieces is used as a series resonator 4. Then the electrode 2 remains as it is at the entire face of one side of the resonator 4 to form an electrode 5 of one face and a small electrode 6 is formed to the other face. Thus, the manufacture steps are simplified and the solvent for eliminating the polarization electrode is not required.

Title: Conveyor and relay device
Inventor: KONISHI SHINICHI
IPC: B66C1/28
Filed: 1993-03-05
Abstract: PURPOSE:To provide a relay device which prevents a held article from falling down due to erroneous signals, erroneous control, electrical shock and the like while it is being carried, precludes the possibility that a receiving terminal comes in contact with each feed terminal unnecessarily when a moving article passes through a specified position, makes both the terminals hardly damaged when they come in contact with each other, and enables both the terminals to be brought into contact with each other positively. CONSTITUTION:The conveyor is made up of a dolly 3 equipped with a holder 9, a motor 11 opening/closing the holder 9 and with a receiving terminal 2, a current feed means 5, 105 and 205 each of which allows a movable element equipped with a feed terminal 4 to be rotatably supported on a rocking stem, and of a control means 7. When the dolly 3 is in each specified position 12, 14 and 16, the feed terminal 4 comes in contact with the receiving terminal 2 owing to the rocking motion of the rocking stem, and the electric motor 11 thereby becomes controllable by the control means 7. Since both the terminals are separated when the dolly 3 is moving while carrying a container, the electric motor 11 will never be erroneously operated by the control means 7. Therefore, the holder 9 will never allow the container to fall down.

Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To confirm whether or not a transaction is left unfinished without burdening the user of electronic money by recording a level in which the transaction of electronic money is normally finished when the transaction of electronic money is not normally finished, and automatically transmitting the information to a processing system. SOLUTION: The history of the transfer of a message in an electronic money transaction to be operated between two sides is obtained by both a paying side and a receiving side. When the transaction is ended unabashed, the information is recorded as unfinished transaction information, and automatically transmitted to an unfinished transaction judging system 12. The unfinished transaction judging system 12 searches the pair of unfinished transaction information records generated in the same transaction by retrieving it by using a data item in each record as a key, and judges whether or not the transaction is actually left unfinished according to the information.
